Undefined authenticated? method in Rails 4

I'm reading a book (Beginning Rails 3), but trying everything on Rails 4.

So, I have one problem:

  def self.authenticate(email, password)
    user = where('email = ?', email)
    return user if user && user.authenticated?(password)
  end

  def authenticated?(password)
    self.hashed_password == encrypt(password)
  end

When I do that in rails console:

User.authenticate('[email protected]', 123)

Rails returns me an error, Undefined method authenticated?.

  irb(main):034:0> User.authenticate('[email protected]', 123)
  NoMethodError:   ←[1m←[35mUser Load (1.0ms)←[0m  SELECT "users".* FROM "users" WHERE (email = '[email protected]')
  undefined method `authenticated?' for #<ActiveRecord::Relation []>

          from bin/rails:4:in `require'
          from bin/rails:4:in `<main>'
  irb(main):035:0>

What's wrong?

instead of user = where('email = ?', email) you should have user = where('email = ?', email).first
